Clinical analytics company Medial Earlysign Ltd. is expanding an existing partnership with Roche Holding AG to commercialize an artificial intelligence (AI) solution for the early detection of lung cancer. The companies originally signed an agreement in September to develop a personalized health solution for early detection of gastric cancer. The goal of the new collaboration is to develop Earlysign’s Lungflag software, which uses machine learning to identify patients at risk of developing lung cancer.
